CO2 and RH/T Sensor Module

For HVAC and Air Quality Applications

CMOSens® Technology for IR detection enables highly accurate carbon dioxide measurement at a competitive price. Along with NDIR measurement technology for CO2 detection, a best-in-class Sensirion humidity and temperature sensor is also integrated on the same sensor module. Ambient humidity and temperature can be outputted by Sensirion's algorithm expertise through modelling and compensation of external heat sources without the requirement of any additional components.

Product Highlight

Liquid Flow Sensor for Biomedical Applications

The single-use liquid flow sensor LD20 enables fast, precise and reliable measurement of the lowest flow rates. The new flow sensor series is based on a successful design study that was first presented in 2014 and has already received several international awards. Product development of the LD20-2600B, the first representative of the new single-use sensor series, is now complete and it is ready for high-volume production. The intelligent, compact and cost-effective sensor is suitable for a wide range of biomedical applications in the field of critical and home care.
